초록
The aim of this paper is to illustrate which factors influence the martensite grain fineness made by subsequently surface carburizing of extruded component. The effects of surface decarburizing by annealing, residual stress, initial microstructure and crystal oriental made by forward extrusion were taken into account. The available evidence suggests that the residual stress inside crystal or the crystal orientation is the main factor that results coarse martensite while cold extruded component was treated by carburizing.
